Super Tuesday’s history is littered with the bones of presidential campaigns. In an average post 2008 election year, upwards of 20% of available delegates are up for grabs.

In 2020, Super Tuesday was instrumental in securing President Joe Biden’s victory. Up until then, Biden had been struggling in early-voting states. But the day before Super Tuesday, many moderate Democrats dropped out and endorsed Biden. Biden swept 10 out of the 14 states, winning 53% of the delegates and solidifying his victory as the Democratic nominee.

In 2016 there were two days that the media deemed “Super Tuesday I & II”. On Super Tuesday I almost half of the remaining delegates required for victory were up for grabs, but on Super Tuesday II four states with winner-take-all delegate distribution were up for grabs.

Former President Trump won a plurality of delegates on Super Tuesday I and a majority on Super Tuesday II, all but locking down the nomination for him.
